Hello All,
Just got my printer up and running. Everything is great for the most part but I have noticed that at the end of the print, the print head seems to jam itself into the front left corner of the build space. It does this pretty violently and always knocks off the cover of the print head. Is this supposed to do this? Is there a setting that I have missed somewhere? Hope someone out there has experienced this and has a remedy.
Thanks,
K2
Just got my printer and I’m having the same problem.
Try a factory reset.
I am having the same issue. Tried factory reset, check belt tensions, Rods are clean and recalibrated multiple times. Printer is only 3 days old. Printed fine then out of nowhere it hit the front left corner and wont stop doing it now. Anyone find a fix? I opened a ticket and am waiting to hear back.
Same here! Sometimes it’s in the middle of the print and other times it’s literally at 99% when it falls off.
Just circling back here, if you’re having this issue. Make sure to unplug anything connected to the usb port on the back of the AP board (P series). I found that on one of my P1S that it would constantly have a tool head error when I had something plugged into that usb port. Very odd and seemingly unrelated but maybe it will help someone else.
Has anyone found a resolution to this??
I am beginning to have the same issues, has anyone been able to fix it? Suggestions?
I’m not sure about the original OPs problem of the print head ramming the front corner of the printer, but if you guys are just having the cover fall off randomly during prints it’s probably one of two things. Either the glue that holds the magnets in place has given out (you’ll see they are missing from one side and still stuck to the magnet on the other side) or the magnets are just wearing out from the heat. This was happening on my two X1Cs that I use to print high temp materials. So my solution, and I know this is less than ideal, is I bought long, heat resistant zip ties. I put one zip tie around each tool head, right below the cutter arm. Cut the extra off and position it where the connection is on the side with the lidar so it doesn’t bump anything when the tool head is moving around. I know this is not an elegant solution but I tried re-gluing the magnets and it just happens again. You can still slide the zip tie off the bottom if you need to remove the cover to work on something, that way you aren’t using a new one each time. If anyone has any better solutions I’m all ears.
Did you get to the bottom of this? Thanks
I just uot my p1s today. Finished the print then ramed the front left until this cover fell off. Did it everytime i started the print back. Doesnt seem to be an issue they resolved. Did i get a bad printer?
Welcome to the forum.
Does the printer exhibit the same behavior when you print one of the prints what was included on the SD card?
I have not tried that yet. I did print a small print in place box after and this did not happen. So maybe it was the benchy file I used. I have only printed these two things so far. It was strange because the benchy was done. It was at 99% and just started ramming itself all the way forward over and over until it knocked the cover off. I putt the cover back on about 4 times and it kept happening. I stopped it then because apparently the pause button, on the app at least, does not actually stop anything. Just makes the head do some pattern then park itself in the back. None of the buttons seem to be able to move it even on the printer itself. So not sure what to do when it does this. Anyway when it ripped the connector off I called it quits for that print.
Were you printing a file that you loaded onto the SD card? The most common reason for a printer to act this way is when the gcode is run on it that is slice for a different printer. Bambu Studio will pop up an error if the wrong printer is selected when you “Print” but this check isn’t in place when you print from the SD card.
No the two prints I have done so far are form the Handy app. I have not done anything from a computer yet. I made sure it was the p1s. It was one of the options the handy app gave me to print for 10 points. Beginner tasks I think it was called. I was to just print from about 20 options and I picked the benchy.
Having same problem all of a sudden on my P1S. It’s almost a year old, few thousand hours. Just started doing this and does it on every print no matter what I try to adjust or fix.
Have you tried a factory reset? Do the pre sliced models that come with the printer do the same thing?
I have been having the same issue for over a year now. Finally I gave up and used a thermal tape to attach the front housing to the mid housing. It looks awful but does the job. The magnets are a good concept if they work. I am hoping that Bambulab will address this issue soon.
Is there a resolution for this issue, I just bought a P1S Dec 24 and it keeps happening every time I print. The first 3 prints were great, now bang the cover goes off and string everywhere.
I am having the same issue since two days. The first prints were perfect but now it happens almost during every print. It is astonishing that this seems to be a known problem but no fix. I woll try to do a factory reset and these test prints. Hopefully this will solve this issue.
